Cannon Sports Ball Repair Sealant for Soccer, Basketball, Volleyball, & Playground Balls (Pint, 16 Ounces)

The puncture seal worked fine after I finally figured out how much 1/2 ounce was. I kept guessing the amount and it didnt work. When I used a container that had ounces marked on the outside I realized I didnt put in nearly enough sealant. I repaired two basketballs so far. They have been holding air for over a month now. Good stuff.

This is great stuff. I am thrilled.

Nine of my eleven volleyballs were leaking air from their valves, and I was getting tired of pumping them up each time I train my daughter. I tried all the Youtube DIY fixes to no avail. So I ordered this stuff as a last resort. It worked for every ball! I used these syringes bought here on Amazon... https://www.amazon.com/gp/product/B01MDR7KLP/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 And tried with 30 ml first, three syringe fills, because I was afraid of weighing the balls down too much. Anything less than this amount never worked. Try this amount first, then add more if needed. My daughter did not feel a weight difference. I stored the balls at first with the valve down so that the goop would seal the valve better, but Im not sure if that was needed. This stuff worked for me. Good luck.

After awhile the sealant dries up and rolls around inside the ball ruining the balance

I followed all the suggestions by other reviewers and this stuff worked perfectly. We live in the desert southwest and our basketball court is surrounded by cacti and agave. I know, not the most logical thing to do, but thats the situation. We have four basketballs lying around that have been punctured at one time or another over the last three or four years. My youngest son had a nice behavioral accomplishment (I wont get into details) so I rewarded him with a new basketball. Needless to say, within about 45 minutes it had been punctured by an agave. I had cut off the spines from all of the agave, but apparently I had missed one. That was the last straw. Instead of buying another ball, I decided to try to patch them all. I found this stuff and it worked like a charm. In summary: 1. Partially deflate ball. I inserted a ball inflation needle without the pump and just squeezed the ball to let air out. 2. Push in 1 oz (30 mL for all the metric people) through the ball inflation needle using a 5 mL medicine syringe (thanks to reviewer who suggested this!). Obviously, it takes 6 syringes-full if its a 5 mL syringe. It may take less because one time I forgot how many times I had used the syringe. I may have only put in 25 mL. 3. Inflate ball to normal pressure. 4. Take ball out and bounce it for a few minutes. 5. Enjoy your new, rock-hard ball. Of all the balls in the yard, only one did not work. This was one where my son had stapled duct tape to the ball with a staple gun in hopes of patching the holes. There were also some deep gouges in the ball. Surprisingly, the air stopped leaking out of 3 of the 4 staple gun holes, but some of the holes were just too large for this to be effective. In other words, if your ball has a gigantic gash or hole in it, this probably wont work. I highly recommend this product for basketballs. Not sure why it didnt work for other people....`

Works fine in a soccer ball.......... :) I recommended. I love it. Good hell yeah 10 times better than buying a new ball :)

I purchased this product largely based on user reviews that indicated this product actually works as expected. I have not been disappointed and have repaired multiple balls saving our team many times the cost of this product in new balls.

Worked just as you said.

Ridiculous!!! Mine came without any way to use it!!!

The order came in a timely manner and great quality. Thank YOU!!
